KNITTING-MACHINE.

To all whom it may concern LIAMS, a citizen of the United States, re-

siding ,in Ogontz, Montgomery county, Pennsylvania, have invented certain Improvements in Knitting-Machines, of which the following is a specification.

The object of my invention is to provide, in a knitting machine having a rotating needle cylinder, means for properly leveling. in respect to the cylinder the dial carrying the needles or other instrumentalities which cooperate with the needles,-an object which I attain in the manner hereinafter set forth, reference being had to the accompanying drawing, which represents, in vertical section, suliicient of a rib knitting machine to illustrate my invention.

In the drawing, 1 represents the fixed table or bed of the machine, upon which is mounted, so as to be readily rotatable, a ring 2 which carriesthe needle cylinder'3, rotating movement being imparted to said ring 2 by means of a drive ring 1 having bevel teeth 5 which mesh with the teeth of the bevel wheel 6 on the driving shaft 7 of the machine, the ring 2 being normally secured to the drive ring 4 by means of one or more bolts, each adapted to an opening 8 in the ring 2 and to a threaded opening 9' in the drive ring 1. I

Mounted upon the bed 1 is the cam ring 10, which carries the needle actuating cams 11, the latter constituting a sectional ring between which and the ring 10 are introduced filling pieces or blocks 12, whereby the cams 11 are held in proper radial position for acting upon the butts of the needles uided in the grooves of the needle cylinder 23 these blocks being detachable in order to permit of the outward movemeritof the cams 11 when it becomes desirable to free the butts of the needles from the influence of these cams in order to permit of the removal of the cams from the machine, or for other purposes.

To the bed 1 is secured a ring 13 which overlaps a flange on the cam ring 10 and serves to retain the same in its proper ver tical position upon the bed 1 Posts 14 on the cam ring carry a yoke 15 and depending from the latter is a shaft 16 having secured to its lower end a collar 16 upon which rests the, hub 17 of the needle dial 18, a dial'cam plate 19 surmounting the Specification of Letters Patent.

latter and having a hub 20 which is secured by a set screw 21, or other suitable means, to the depending shaft 16. The yoke 15 is provided with means for laterally .adjusting or tilting the depending shaft 16 so as to accurately level the needle dial 18 in respect to the needle cylinder 3 and thus insure the accurate spacing of all portions of the pcriphery of the needle dial in respect to the upper edge of the needle cylinder in order to. efiect the production 01: uniform stitches upon all of the needles of the machine. In

the present instance this adjusting mechanism is similar to that set forth in Letters Patent- No. 421,147, dated February 11, 1890, and consists of a sleeve or bushing 22 surrounding and snugly fitting to the shaft 16 and acted upon by upper and lower series of adjusting screws 23 and 21 carried by a central hub 25 on'the yoke 15. 'lVhen, as in the patented structure, the needle cylinder andv dial were stationary and the can'rring 10 and dial cam plate 19 were rotated with the depending shaft 16 any departure of the needle dial from its proper'level in respect to the cylinder could be readily detected, as the rotation of the shaft 16 caused a vibration of the needle dial and therefore caused the periphery ofthe same to rise and fall in respect to any part of the upper edgeof the cylinder to an extent proport onate to the displacement of the shaft 1611-0111 its true position.

lVhen, however, the machine is one having a rotating needle cylinder and correspondingly rotated needle dial and a stationary cam ring and dial cam plate displacement of the stationary shaft- 16 simply imparts a permanent tilt to the needle dial so that the periphery of the same at one side of the machine is farther removed from the upper edge of the needle cylinder than at the other side of the machine, and even although this difference is too slight to be readily detected by the eye the difference in the size of the stitches resulting from this displacement seriously impairs the character of the knitted fabric produced upon the machine. In

" order to overcome this objection. I so construct the machine that either the needle lot"- I 1 ring and dial'cam cap being rotated and the needle cylinder and needle dial being stationary during the time that the adjustment of the needle dial is being effected. The most convenient way of effecting this result is to provide the cam ring 10 with an opening 26 and the drive ring 4 with a second threaded opening similar to the opening 9 for the reception of each of the bolts 27 whereby the rotating members of the machine are to be fastened together, each securing bolt being applied to an opening 8 of the cylinder carrying ring 2 and to an inner opening 9 of thedrive ring when theneedle, cylinder and needle dial are to be rotated in the normal or knitting operation of the machine, and each of the securing bolts being adapted to ail-opening 26 in the cam ring andto an outer threaded opening in the drive ring when the cam ring, dial camplate and shaft 16 are to be rotated, as when the leveling of the dial is being effected, either the same or a different set of bolts being used for, each operation, and it being understood, of .course, that when either the cylinder? carrying ring 2 or cam ring 10 is disconnected from the drive l-iugthe latter willimpart no rotating movementto it. 1 i

The needle cylinder and needle dial are locked together for or movement by any of the usual means, those shown in the, present instance being engaging lugs 28and 29 projecting respectively; from the interior of the needle cylinder and from the under side of the needle dial.

It is not'essential to n'iy 'invention that both the cylinder and. the cam ring should be driven from the same drive ring, as the cam ring may, if desired, have independent means for rotating it, or thesha't't16 may be rotated independently of the yoke 15 during the leveling operation, if desired, or by to a plain knitting I in the other against. rotating chine having both a needle cylinder and a needle dial, said invention is also applicable machine having a dial which carries instrumntalities other than needles for acting uponthe yarn or fabric, or for cooperating with the needlesof the cylinder in any manner, as in such case, it

may be justas necessary or desirable as in a rib knitting machine to have the dial and cylinder bear a uniform relation to each other during-the knitting operation.
